By law, anyone who gives driving instruction for money should display a green DSA issued octagon Licence on the windscreen of their training car. Trainee instructors may give instruction during the final part of their Instructor training but they must display a pink triangular License. The instructor is a fully qualified DSA Green licence holder.

All instructors have to undergo periodic check tests by DSA (Driving Standards Agency) senior examiners to ensure methods of instruction are of a good standard. Instructors are graded from 1 - 6 and a score of below four would require the instructor to improve his standard of teaching. I am a grade 5 instructor which means my instruction is classified as of a good overall standard. I already hold a CRB police check certificate which will be mandatory for all ADI's shortly.
